Swiss Researchers Unveil Fast, Robust Qubit Creation Method

11/28/2025

Summary

Story summary

Researchers from the University of Basel, Switzerland, have developed a method to create qubits that are fast and robust.
They use a germanium wire coated with silicon to generate hole-based qubit states.
By tuning an external electric field, they optimize spin-orbit interaction to achieve high coherence without sacrificing speed.
The work, published in Nature Communications, acknowledges challenges in precise qubit-device fabrication that limit scalability.
